In the construction illustrated in detail in e5 are disposed in perpendicular relation with Figures 2 and 3 the blank is of substantially rectangular form withthe plate 10 constituting the major portion of'the blank and adapted to be bent on a foldiline l7to form a triangular bracing fiap l8 ofiwhich the outer edges'carry the wings l5 and 16, so a that when the bracing'flap is 'foldedas indicated in Figure 2 into parallelism withthe body portion of the' platef it defines angularly disposed webs adapted to fit into the l lrerfsor slits of the frame members while the portion of the plate ivhichisoverlapped :by the flap constitutes a brace'sp'anningthe angle, between the frame members and rein- ..forced by thefiap.
